CORRUGATED PAPER-BOARD.

. To all whom it may concern: I

Be it known that I, JEFFREY T. Fnnans, a citizen of the United States, residing at' Anderson, Madison county, Indiana, have in- 5 vented certain new and useful Im rovements in Corrugated Pa er-Board, of w 'ch the following is a spec' cation. I

My invention relates to corru ated board, more particularly the I in type and the object thereof is to provide means for reinforcing or stiffening one or more of the edges of such board. I

My invention has special, but not exclusive, application 1 5 known as calen paper- -mailers, which requlre to be particularl stifi in order to prevent the 031?]: are from eing bent or broken in the Various other'features of advantage and 2e utility of my invention will be understood from the description hereinafter given.

In the drawings Figure 1 is a perspective of a cplendar-mailer embodying my invention; ig. 2, a side or edge elevation thereof, 2 5 andFig. 3 aperspeetive 0 one of the strength; ening-strips shown ready for insertion in the paper-board. r or purposes of convenient illustration and description I have shown my invention as apo plied to a calendar-mailer; but it will be unerstood that my invention is not to be limited to this particular use of corrugated paper-board, but that I contem late using my mvention wherever applicab e. As shown 3 5 thecalendar-mailer com rises a corrugate V paper-board A of suitab e size and dimensions and provided with the paper flap A,

one of whose edges is secured in suitable.

manner tol one side of the paper-board. 4o The paper-board A, which 1s to bestrengthened 6r stiffened at one or more of its e ges for the pur oses hereinbefore stated, is what is con'nno y known as double-faced corrugated paper or board, comprising the two 45 facing-stri s a and a and the intermediate corrugate paper a. The strengtheningstrips, which, as shovm in Fig. 1, aretwo 1n num er, consist of wood strips or veneer B, preference are driven or crowded in w c b so. in suite. is manner through the corrugations and preferably across such corrugations, as Asben n Figs. 1 and 2.

referred to insert the stripsa short distance om the edge of. the corrugated, sheetsa 55 about one-half an inch therefrom-sue strips not, only preventing bending of the board or sheet, but also preventing the corners of the sheet from being crushed down, which has been a serious fault "with the old Although I prefer to insert or force the wood strips or veneer through the body of the corrugations, as above explained, yet it is possible to apply the wood strips by pl 0- ing them III-PQSltlOIi on t d h 1 op of the (pohrglungtionsantena tesecon' sheet over them. It% be understood that such modification is within the scope of my invention. 7c In practice the wood strips or pieces B are inserted by machinery which ap lies glue, gum, or other similar substances to otli sides of the stick. In order to enable the strips to be forced or driven readily through the cor- 7 rugations, such-strips are'first sharpened at one end and are forced through the sheet so as to protrude therefrom, say about threefourths of an inch on the o posite' side. The strips are thereupdn cut 0% smooth with the E edge of the sheet, \or, if desired, instead of sharpening the strips the same before being driven may be inser ed in a metal point havng a socket at its rear end, and thereu on forced through the 1 sheet or board, a ter which such metal point can be removed and placed on another strip to be forced through the sheet or board. x

asmuch as corru ated paper-board is more liable to bend or reak longitudinally of, the corrugations, it is preferable to insert the reinforcing or stifi'eningistrips transversely of such corrugations, as is shown in Figs. 1 {and 2; but it will be understood-that some measure of my invention may be obtained by insorting such strips longitudinally of the Jcorrugations. 1

Corrugated paper-board rovided with strips as hereinbefore descri ed has nearly the same strength and resistance as a solid 1. wooden board, withall liability of bending in the body or crushing at the corners prevented.
